This is a Corelle plate purchased in Brimfield, Massachusetts, a famous antique town in the United States. It's from the Old Corelle Christmas series, a limited edition from 1989. It reflects American culture at the time and is a very lovely plate. It measures approximately 26cm in diameter and 2cm in height. I am also listing other plates from the same Christmas series, from 1985, 1986, 1990, 1992, and 1993.
